A technique for using memory attributes to relay information to a program or other agent. More particularly, embodiments of the invention relate to using memory attribute bits to check various memory properties in an efficient manner.

Technique for using memory attributes

Methods and systems are provided for managing memory allocations and deallocations while in transactional code, including nested transactional code. The methods and systems manage transactional memory operations by using identifiers, such as sequence numbers, to handle memory management in transactions. The methods and systems also maintain lists of deferred actions to be performed at transaction abort and commit times. A number of memory management routines associated with one or more transactions examine the transaction sequence number of the current transaction, manipulate commit and/or undo logs, and set/use the transaction sequence number of an associated object, but are not so limited. The methods and systems provide for memory allocation and deallocations within transactional code while preserving transactional semantics. Other embodiments are described and claimed.

System and method for allocating and deallocating memory within transactional code

A system includes a processor and a size bounded first-in first-out (FIFO) memory that is connected to the processor and a display is connected to the processor. A managing process to run on the processor to manage the FIFO memory structure. The FIFO memory includes a counter portion and a value portion for each of a tail portion and a head portion, and the managing process is non-blocking. The counter portion is used as a timestamp to maintain FIFO order.

Lock-free bounded FIFO queue mechanism
